The Broncos signed seventh-round draft pick and third-string quarterback Zac Dysert of Miami (Ohio) to a four-year contract Monday that included a $48,200 signing bonus.Now Dysert goes to work on making the 53-man roster."I was talking to my agent (Mike McCart ney, son of College Football Hall of Fame coach Bill McCartney) before the draft, and this was our No. 1 pick," Dysert said. "Everything worked out perfectly. I did take a visit here—loved it from the minute I got here. It was like, 'God's got a perfect plan for me, and this is the place for me for his plan to work out great.' I'm here for a reason, so I'm just going to take it as best as I can and run with the opportunity that I have."The Broncos kept three quarterbacks last year because No. 2 Brock Osweiler was a rookie and No. 3 Caleb Hanie was veteran insurance.But now that Osweiler is the most experienced of the backups to Peyton Manning, it's possible the Broncos will have only two quarterbacks on their roster.
